No officer, director, or employee of any corporation or unincorporated association, no partner, or employee of any partnership, and no individual, primarily engaged in the issue, flotation, underwriting, public sale, or distribution, at wholesale, or retail, or through syndicate participation, of stocks, bonds, or other similar securities, shall serve the same time (sic) as an officer, director, or employee of any member bank * * *
* * * in acting as specialists on the New York Curb Exchange, it is necessary for the firm to buy and sell odd lots and * * * in order to protect its position after such transactions have been made, the firm sells or buys shares in lots of 100 or multiples thereof in order to reduce its position in the stock in question to the smallest amount possible by this method. It appears therefore that, in connection with these transactions, the firm is neither trading in the stock in question or taking a position in it except to the extent made necessary by the fact that it deals in odd lots and cannot complete the transactions by purchases and sales on the floor of the exchange except to the nearest 100 share amount.
